The emitting antenna of a \(100-\mathrm{kW}\) radio station radiates equally in all directions. What are the magnitudes \(E_{\max }\) and \(B_{\max }(a) 100 \mathrm{~m}\) from the antenna and \((b) 50 \mathrm{~km}\) from the antenna? (c) For these two distances from the antenna, calculate the maximum potential difference caused between the ends of a receiving antenna that is \(1.0 \mathrm{~m}\) long, assuming the antenna is aligned perfectly with the electric field of the radio wave.
